Miami -LRB- CNN -RRB- -- After weeks on the run and days in immigration detention , American technology pioneer John McAfee arrived in Miami on Wednesday .

He said he had no choice in the matter , that Guatemalan authorities expelled him to the United States and put him on a plane to a destination they determined .

`` I was whisked out of prison , '' McAfee told CNN affiliate broadcaster WSVN in front of his South Beach hotel . `` I was forcibly separated from Samantha , and now here I am . ''

Samantha Venegas is McAfee 's girlfriend .

When the plane landed , U.S. officials boarded the aircraft to greet him and escort him off .

It was unclear whether he planned to stay in Miami or where he might go next .

For the past week , McAfee waged a public battle , requesting an asylum in Guatemala and arguing that police in Belize were persecuting him . Authorities turned down his request and told him he would have to leave the country .

`` He opted to return to his country of origin , '' said attorney Telesforo Guerra , who has represented McAfee since he arrived in Guatemala last week .

Authorities in Belize , where McAfee had lived since 2008 , say they want to talk to McAfee about the November 11 killing of his neighbor , American businessman Gregory Faull .

McAfee said he had nothing to do with the death and insists he left Belize to escape police persecution .

Guatemalan authorities took him into custody on accusations of entering the country illegally , and his asylum bid was rejected .

McAfee told WSVN he has openly criticized Belize 's government for seven months , making himself a `` thorn in their side . ''

`` Unfortunately , now that I 'm here , they ca n't shut me up , '' he said .
